About

Boulder Nonlinear Systems

Boulder Nonlinear Systems, Inc. designs, manufactures and sells liquid crystal based photonics devices and systems. The company is experienced in developing components based on the highest performance ferroelectric and nematic liquid crystals.

A Colorado company specializing in opto-electronic devices based upon advanced liquid crystal technology BNS builds unique analog liquid crystal on silicon modulators used in applications ranging from holographic storage to microscopic cell manipulation. The company's advanced liquid crystal technology is used in telecommunications, medical instruments, defense, and manufacturing.

History

The company was founded in 1988 by Steve Serati. With a background in electrical engineering and liquid crystal optics, he began by building optical processors and phased array beamsteerers for LIDAR applications. The company gained a reputation for innovative research and development in optical systems. Over the years, the projects have grown in optical processing and leading edge optical components. Today, companies from all over the world call on BNS’s decades of experience in liquid crystal design and manufacturing. Its customer base, including fortune 100 companies, purchases devices built in state of the art clean room facilities located in Lafayette, Colorado.

Mission

The BNS corporate mission is to advance the state of the art in liquid crystal device theory, design and fabrication and translate this advanced technology into quality products for a variety of commercial and industrial applications.

Technology

The BNS signature product is its family of analog liquid crystal on silicon (LCOS) spatial light modulators. These devices are used to modulate a beam of incident light in order to add information to it, or to shape, correct, or steer it. A unique feature of the BNS LCOS devices is their analog mode of operation. Most such modulators are binary devices which have an on and an off state. The BNS analog devices offer analog modulation that permits up to 256 optical states of the device. This analog operation allows a superior ability to control the beam of light. BNS spatial light modulators offer very high frame rate operation including refresh rates as high as 18-Khz. Although these rates are much higher than necessary for human interaction, they allow machine vision rates of operation never before available.

The analog operation also allows construction of liquid crystal devices for applications that have never before existed. The company’s award winning non-mechanical beam steering device can control the reflected angle of a beam of light under computer control. This has opened exciting new frontiers in optical storage and telecommunications.

Component Product Family

The company offers its Spatial Light Modulator systems in resolutions of 256x256, and 512x512. It also offers a beam steering system based upon its 1x4096 linear array device. BNS also offers Liquid Crystal on Glass (LCOG) devices for a variety of applications. These devices include tunable filters, optical shutters, variable retarders, and polarization rotators.
